ABSTRACT:
A coating method for a color filter, including the steps of: coating a first photoresist layer on a substrate; forming at least a aligning pattern and a first color film pattern on the first photoresist layer by exposure and development; coating a first dye on the aligning pattern and the first color film pattern; stripping the first photoresist layer; coating a second photoresist layer on the substrate, wherein the aligning pattern and the first color film pattern are formed on the substrate; aligning position by using the aligning pattern of the substrate; forming a second color film pattern on the second photoresist layer by exposure and development; coating a second dye on the second color film pattern; and stripping the second photoresist layer. The invention also discloses an aligning-assembling method for a color wheel, which includes the color filter.
